Description

Technical Field

[0001] This utility model relates to the field of automotive interior parts processing technology, and in particular to an automotive interior parts forming clamping mechanism. Background Technology

[0002] In the molding process of automotive interior parts, clamping mechanisms are often used around the mold. This can easily cause wrinkles in the product during molding. Some customers want to use a simple mechanical mechanism to clamp the material frame. The mechanism below can achieve the clamping function without air connection, thus obtaining a better product. Utility Model Content

[0003] In order to solve the problems existing in the prior art, the present invention provides a clamping mechanism for manufacturing automotive interior parts that can achieve molding without air connection.

[0004] The technical solution adopted by this utility model to solve its technical problem is: A clamping mechanism for forming automotive interior parts includes a nitrogen spring 1, a nitrogen spring fixing plate 2, a nitrogen spring limiting plate A3, a nitrogen spring limiting plate B4, a material frame 5, a fixing block 6, a pin block 7, a limiting block 8, and a handle 9. The nitrogen spring 1 is bolted to the nitrogen spring fixing plate 2 and is located on the side of the mold core. The nitrogen spring fixing plate 2 is bolted to both the nitrogen spring 1 and the mold core. The nitrogen spring limiting plate A3 is bolted to the mold core. The material frame 5 is fixed to the mold core via a guide block and forms the material by clamping it. The fixing block 6 is bolted to the material frame 5. The pin block 7 is fixed in a through hole in the fixing block 6. The limiting block 8 is bolted to the material frame 5. The handle 9 is fixed to the pin block 7 for easy pushing and pulling by the worker.

[0005] This utility model also has the following additional technical features: As a further specific optimization of the technical solution of this utility model: the function of the nitrogen spring 1 is to drive the pressure frame on the side of the mold core to press the material when the mold is closed, so as to prevent wrinkles from appearing in the product during the molding process, and at the same time save materials.

[0006] As a further specific optimization of the technical solution of this utility model: the nitrogen spring fixing plate 2 serves as a carrier to fix the nitrogen spring 1 and the mold core.

[0007] As a further specific optimization of the technical solution of this utility model: the nitrogen spring limiting plate A3 ensures that the nitrogen spring 1 is limited in the working position and the storage position, and prevents the nitrogen spring limiting plate B4 from moving during the production process.

[0008] As a further specific optimization of the technical solution of this utility model: the nitrogen spring limiting plate B4 is fixed to the mold core by bolts. The nitrogen spring limiting plate B4 ensures the working state of the nitrogen spring 1. When pushed in, it is in the working position. The nitrogen spring 1 acts on this plate to drive the material frame to be pressed. After being pulled out, the force of the nitrogen spring 1 cannot be applied to the material frame 5, ensuring that the nitrogen spring 1 is not under force when the mold is stored.

[0009] As a further specific optimization of the technical solution of this utility model: the fixing block 6 is provided with a through hole for fixing the pin block 7.

[0010] As a further specific optimization of the technical solution of this utility model: the function of the pin block 7 is to pull out the nitrogen spring 1 to the storage position. At this time, the nitrogen spring 1 does not exert any force on the material frame 5. After the nitrogen spring 1 is pushed in, it is in the working position. The nitrogen spring 1 exerts force on the material frame 5 through the pin block 7.

[0011] As a further specific optimization of the technical solution of this utility model: the limiting block 8 is provided with a through hole for fixing the pin block 7.

[0012] Compared with the prior art, the advantages of this utility model are: When the mold is in the working position, pushing the handle forward allows the nitrogen spring to press against the pin block, thus ensuring the ejection of the material frame. When the mold is stored and not in operation, pulling the handle backward locks it in place by the limit block, ensuring that the nitrogen spring and the material frame do not come into contact.

[0015] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings.

[0016] A clamping mechanism for forming automotive interior parts includes a nitrogen spring 1, a nitrogen spring fixing plate 2, a nitrogen spring limiting plate A3, a nitrogen spring limiting plate B4, a material frame 5, a fixing block 6, a pin block 7, a limiting block 8, and a handle 9.

[0017] Normally, the material frame on an automotive interior parts mold is driven up and down by a cylinder. However, some equipment lacks a pneumatic power source, so alternative methods must be used. This invention uses a nitrogen spring to drive the material frame. Since nitrogen springs are constantly under stress, prolonged compression of the nitrogen spring could lead to cylinder explosions or other safety accidents during mold storage. This structure aims to prevent such explosions. A pin ensures that the nitrogen spring's force is applied to the material frame when in the working position. When stored, the pin is pulled out and the mold is closed, preventing the nitrogen spring from acting on the material frame. This increases the lifespan of the nitrogen spring and enhances safety.

[0018] The nitrogen spring 1 is fixed to the nitrogen spring fixing plate 2 by bolts and is located on the side of the mold core. The function of the nitrogen spring 1 is to drive the pressure frame on the side of the mold core to press the material when the mold is closed, so as to prevent wrinkles from appearing in the product during the molding process and save materials.

[0019] The nitrogen spring fixing plate 2 fixes the nitrogen spring 1 and the mold core respectively by bolts. The function of the nitrogen spring fixing plate 2 is to serve as a carrier to fix the nitrogen spring 1 and the mold core.

[0020] The nitrogen spring limiting plate A3 is fixed to the mold core by bolts. The nitrogen spring limiting plate A3 ensures that the nitrogen spring 1 is limited in the working position and storage position, and prevents the nitrogen spring limiting plate B4 from moving during the production process.

[0021] The nitrogen spring limiting plate B4 is fixed to the mold core by bolts. The nitrogen spring limiting plate B4 ensures the working state of the nitrogen spring 1. When pushed in, it is in the working position, and the nitrogen spring 1 acts on this plate to drive the material frame to be pressed. When pulled out, the force of the nitrogen spring 1 can no longer act on the material frame 5, ensuring that the nitrogen spring 1 is not under force when the mold is stored. The material frame 5 is fixedly installed on the mold core by a guide block, and the material frame 5 achieves material forming by pressing the material.

[0022] The fixing block 6 is fixed to the material frame 5 by bolts, and the fixing block 6 has a through hole for fixing the pin block 7.

[0023] The pin block 7 is fixed in the through hole of the fixing block 6. The function of the pin block 7 is to pull out the nitrogen spring 1 to the storage position. At this time, the nitrogen spring 1 does not exert any force on the material frame 5. After the nitrogen spring 1 is pushed in, it is in the working position. The nitrogen spring 1 exerts force on the material frame 5 through the pin block 7.

[0024] The limiting block 8 is fixed to the material frame 5 by bolts, and the limiting block 8 has a through hole for fixing the pin block 7.

[0025] The handle 9 is fixed to the pin block 7, making it convenient for workers to push and pull the pin block 7.

[0026] The above detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.
